Question for those who have or had the 60-75 mph shimmy
This is old but new info to me
I don't remember seeing this TSB I did a lot (spent a lot) trying to fix the shimmy in my car. I replaced all the tires, one rim and then I even took it to another shop to get the road force balance done to see it it would clear up the rest of it. The road force balance showed all my wheels were within spec (Number was like 12 at most per wheel). My dealer also checked the rear alignment and it was good too. Front aligment was done when they replaced the rack.
I wonder if anyone here has had this done and did it help?
If Major Guard covers this, it would be the first attempt to get this fixed that I wouldn't have to pay for. 
Archon, Thanks for posting this info
Anybody have this done, if so, did it help?

8. Replace both lower control arms on vehicles built prior to the VIN breakpoints shown. On Aurora, Bonneville, DeVille, Park Avenue, Park Avenue Ultra and Seville models, a newly developed hydro-bushing lower control arm with improved damping characteristics has been released. This control arm is not used on the LeSabre. The new lower control arms may provide an incremental improvement to the vehicle ride. Customers who have become "tuned in" to the shake condition may still feel some shake in the vehicle after the new lower control arms are installed. Refer to Lower Control Arm Replacement, (refer to the Parts Information table below for SI document ID numbers).
Important: THE CONTROL ARMS SHOULD ONLY BE INSTALLED ON VEHICLES IF, AFTER THE TIRE AND WHEEL DIAGNOSIS AND REPAIRS HAVE BEEN PERFORMED, THE VIBRATION CONDITION STILL EXISTS.

I have it and I'm putting money on the Eagle RS-A'* I have. But they are new tires from the dealer so I'll deal with it for awhile. Some days the shake is gone, some days its there.
Weird. :?

I can rule out the Eagle RS-A'* for you. I am running Michelin'* on mine. My shacking is the same, sometimes it does it and sometimes it don't. Sometimes I try to see if I can make it do it but can't. Sometimes it'* worse than other times.
I was hoping there was a chance that this might help because this wasn't attempted on mine yet.

I've checked that TSB a few times, and the addition of the lower control arm is a relatively new addition. However, even reading what they posted, it will be an "incremental" improvement...which to me, means just a little. Whether it would be worth the cost to find out is hard to say. If your warranty will pay for it, it may be worth a shot.

Mine has done that ever since I got it. I think some of it is the oober cheap Super Star tires, some of it is probably in the alignment/steering/suspension system. I have a new clunk in there too that I can't find

I've lived with the shimmy for about 16 months now - Since buying a new set of RS-A'*, I kept having Goodyear try to rebalance my tires but wouldn't help. They insisted it wasn't tire related.
Just gave up and put on 4 new michellins - now the ride is smooth as silk.

but I am sure I am missing a wheel weight on my left front rim.
